有机肥和化肥配合施用对烟叶外观品质和化学成分有良好影响.在等氮磷钾养分条件下,配合施肥可使上等烟比例比单施化肥增加5～9%,且糖碱比更为协调。配合施肥对改善烟叶品质与有机肥促进氮磷钾养分平衡供应有关。此外,通过有机肥与氮肥的相互作用,使养分供应与烟草生长协调,并对碳氮代谢的协调与转换产生有利影响。有机无机配合施肥还有利于土壤硝化过程的进行,施肥二周后,土壤中硝态氮占有效氮的80%以上。 The application of organic manure and chemical fertilizers had a good effect on the appearance quality and chemical composition of tobacco leaves.Under NPK fertilizers, the proportion of superior tobacco increased 5 ~ 9% coordination. With fertilizers to improve the quality of tobacco and organic fertilizer to promote the balanced supply of nitrogen, phosphorus and potassium nutrients. In addition, through the interaction of organic and nitrogen fertilizers, the supply of nutrients is coordinated with the growth of tobacco and has an advantageous effect on the coordination and conversion of carbon and nitrogen metabolism. Organic-inorganic fertilization is also conducive to the process of soil nitrification, fertilization two weeks later, the soil nitrate nitrogen accounted for more than 80% of available nitrogen.
